How to increase Register Page White box width?

I tried the following:

subclass Register and add protected ?string $maxContentWidth = 'full'; Then use my Register class in the Panel registration
override the register blade view and do (added a w-full class)

<x-filament-panels::page.simple class="w-full">

<x-filament-panels::page.simple class="w-full">

<x-filament-panels::page.simple class="w-full">

<x-filament-panels::page.simple class="w-full">

But the register page white box width is still the same
